Abstract

Solid coco-lumber is relatively a new raw material in Malaysia’s furniture industry. However, different situations can be seen in the Philippines and Indonesia as they are actively producing and marketing coconut wood-based products. In this study, the physical and mechanical properties such as moisture content, basic density, Modulus of Rupture (MOR), Modulus of Elasticity (MOE), shear stress, compression parallel to the grain, thickness swelling and water absorption properties of Malaysian solid coco-lumber were determined. The solid coco-lumber was divided into inner and outer parts and were tested under two different conditions i.e. green and air-dry conditions. The study showed that the physical and mechanical properties of the air-dried outer part of the solid coco-lumber were 50% higher compared to the inner part under both conditions. The results proved that the properties of coconut wood tested are very useful to the emerging coco-lumber based furniture industry in Malaysia.

Abstract

A study was undertaken to investigate the physical and mechanical properties of engineered coconut (Cocos nucifera) veneer (ECTV). The coconut trunks (40 – 50 years old) were obtained from Hutan Melintang, Perak and were peeled into veneers at Bestgrade Sdn. Bhd. The veneers were obtained from two different parts of coconut trunks viz inner and outer which were used to fabricate 5-ply engineered coconut veneers. The ECTVs were fabricated at FRIM’s Bio-Composite Laboratory. They were manufactured with urea formaldehyde (UF) resin and with three combinations namely 100% inner, 100% outer and alternate outer & inner veneers (mix). The densities for the engineered veneers made of 100% outer, 100% inner, and mixed layers were 944.1 kg/m3, 858.15 kg/m3 and 891.11 kg/m3, respectively. Results showed that the Modulus of Rupture (MOR) of the ECTV made from 100% outer veneers had the highest mean MOR value (88.69 MPa), followed by those made from the mixed veneers (74.35 MPa) and 100% inner (58.44 MPa), respectively. On the other hand, the Modulus Of Elasticity (MOE) values were 10.12 Mpa for outer, 8,210 Mpa for inner and 10,075 Mpa for mixed. Overall, the testing results showed that the ECTV met the standard requirements.
